GSD3930C04WW General Electric Dishwasher - Instructions

Removed the 4 screws on front inspection plate and had easy access to solenoid switch. Unplugged unit and switched out with repair kit. So easy a caveman could do it...

removed screen at back of dishwasher from the inside. Twisted piston & nut assembly out by hand and replaced with new one. Very, very simple. Dishwasher works perfectly now.

Loosened the clamps connecting the pump, disconnected all electric and stabilizer arm. Simply unscrewed the solenoid bracket and replaced with new part.

took out 4 screws pulled piston out and changed put back together. very easy and inexpensive!! thanks

First let me say, it's so easy even a caveman can do it. I removed the water out of the bottom. Then I removed the cover in the very back of the machine with a wrench. As soon as I did that, I could see the piston. Next, I twisted the white piston out with my fingers (this was the hardest part). I could see the piston had partially disintigrated. I ordered a new one, had it delivered in a few days, and put it all back in reverse. It took minutes. Thanks to the guy that posted his story, I was able to fix mine for $18.

First I opened the dishwasher and removed the lower basket. Next I removed the 4 screws that hold the food filter plate in place at the back of the tub. Then I unscrewed the Piston/Check Valve assembly counterclockwise, located at the back center of the tub, by hand. I replaced the old part with the new one and reinstalled the filter plate. I ran a rinse cycle to verify that that all of the water was purged. Finally, I reinstalled the lower basket and resumed using my dishwasher.

I removed the end caps on the two side tracks using pliers. I pulled out the old rack and inserted the new one. I replaced the end caps and I was done. It was that simple.

Remove the back filter to access check valve assembly. Twist check valve assembly to remove, not significant deterioration of rubber cap. Install new assembly. Re-install filter. Super-easy and effective!

After two repair people were unable to solve the problem, I read similar stories in your forum and decided to replace the check value as a last ditch effort. Looking at your diagrams it seemed like an easy repair. Removed four screws with nutdriver and replaced value by hand. Ran washer three times and water drained completely. Still puzzled that this wasn't the first thing a repair person would check.
Websight very helpful.

Remove shield in rear. Unscrew valve using hand. Screw new valve in place.

repair kit was complete and directions were easy to follow. my model of dishwasher disnt even require any of the adapters. really only required removing a couple of clamps and replacing everything as a single unit

Removed screen bottom rear andfound a plunger type part, unscrewed plunger and found it was distressed around it and did not close of a tight seal. Placed new part into location and dishwasher now proforms perfect...

took end caps off (one broke) slid in new disk rack and put caps back on.

Your video doesn't include disconnecting water supply disconnecting electrical and disconnecting drain hose but after all that the repair to change the solenoid was a easy task but the problem was not solved so I TRIED . thanks Robert

The replacement of the motor and pump assembly went smoothly and without difficulty however this did not fix the problem. It then appeared that the inlet water valve was not operating properly, so this part was ordered and instlled, a very simple proceedure that could be done witrhout removving fthe dishwasher from its cabinet. -- Again failure to run -- the timer assembly and electronic panel were then removed and examined. The control panel had no visible defects, so the timer assemblyand its cover was removed and examined . Uing a variable power supply the drive motor for the timer was energized and tested. As the motor ran properly the electrical switching contacts were then carfully checked, it was discovered that one contact set was heavily pitted and burned. These contacts were carefully cleaned and pollished with 1000 grit sanding paper. The actuator leaves were examined and two sets were found to be slightly out of alignment. The leaves on these sets were bent slightly to insure they were in line with the rest of the leaf serts. It was then noted that the rotating leaf('s) actuator had a home position indicated by a molded depression at one location and the motor was energized using approximately 5 volts ( a nine volt battery could also be used as a poer supply) observing prolper polarity to run the rotator until the home position was established and the actuator rods paul dropped into this depression. The assembly was then replaced in the diswasher using care to make sure that the actuation arm and spring were positioned properly weith the arrow end of the arm located in the recesss of of the rotating timer disk use care in placing the assembly and do not lose the sping which attaches to a mounting post and the arm. You may want to take a picture of the spring and arm locations when you rwmove the timer assembly to properly re-assemble all components, the repaired unit was placed back in its cabinet and a full cycle run to establish proper operation. And unit checked ok! Some of these proceedures are not for the weak of heart. I am a retired engineer who has been repairing my own equipment since graduation. .
